18 Claims. This invention pertains to pin type feeding means for writingand imprinting machines, progressively engageable in longitudinallyspaced 1 holes in continuous strips of record material for advancing itpast a writing position, and more particularly to a traveling series offeeding pins which are automatically extended and retracted intoandoutoifthe longitudinally spaced holes in the strip while the latteris being advanced through a relatively straight path of travel, asoriginallydisclosed and claimed in copending application Serial No.16,008, filed April 12, 1935,

which resulted in' Patent No. 2,112,833 and of which the presentapplication is a division, and to which cross reference is made.

The object of the invention is to improve the construction as well asthe means and mode of operation of .pin type feeding devices for wrlt-'ing and imprinting machines, whereby they will not only be moreeilicient in use but will be automatic in operation, uniform in action,having relatively few operating parts and unlikely to get out of repair.

A further object of the invention is to provide a pin type device havingrelatively loose engagement in longitudinally spaced holes in the recordmaterial, wherein the pins are advanced througha' relatively straightpath of travel whil in" engagement with the record ma- :terial;

A further object of the invention is to provide a traveling carrierhaving extendible and retractable feeding p n to be progressivelyautomatically projected into engagement with the material and withdrawntherefrom at predetermined points in't'heir path of travel.

A further object of the invention is to provide a pin type feeding meanshaving the advantageous structural features and meritoriouscharacteristics herein disclosed.

- With the above primary and other incidental objects in view as willmore fully appear in the specification, the invention consists of thefeatures of construction, the parts and combinations thereof, and themode of operation, or their equivalents as hereinafter described and setforth ins are shown in retracted inoperative relation.

, Fig.- 4 is'a longitudinal sectional view of the construction shown inFigs. 1, 2 and 3. I Fig. 5 illustrates a a portion of its path of traveldisposed in a straight line substantially parallel to the path of travelof the record mafeeding. pins having terial into and out of thelongitudinally spaced holes of which the pins are extendible andretractable, to which form of embodiment of the invention thisdivisional application is particularly directed.

Fig. 6 is a fragmentary view of a portion of record material havingtherein a special T-shaped shown in Fig. 6.

form of feed hole.

Fig. '7 is a detail perspective view of one of the feeding pin elementsillustrated in Figs. 1, 2 and 3 for use with the T-shaped feed holesFig. 8 is a sectional view similar to Figs. 2 and 3 illustrating the useof feeding pins devoid of the paper retaining heads or cross arms shownin preceding figures.

Fig.1 9 is a detail view of the straight type of feeding pins as shownin Fig. 8, to lie-employed in lieu of the headed t p pins shown'in-otherfigures, and which is equally applicable to the endless chain typefeeding device shown in Fig. 5.

Like parts are indicated by similar characters of reference throughoutthe several views.

The purpose of the herein disclosed pin type" feeding device isduo-functional. It not only serves to uniformly advance superposedstrips of record material toward the writing or imprinting position of atypewriter, tabulating. computing or billing machine, or otherimprinting apparatus, but by progressive engagement of the feeding pinssimultaneously in registering longitudinally spaced holes or aperturesin the superposed strips of record material it assures and maintainsregistration of prescribed writing or impression receiving areas thereofas they pass the writing or imprinting position.

There are herein illustrated two forms of apparatus, mom of which theextendible and retractable feeding pins are mounted directly on a platenroll of a writing or imprinting apparatus and actuated into and out offeeding engagement with the record material by the rotation of suchplaten roll, which construction forms the subject matter of the parentapplication. In the other form of apparatus .to which the presentdivisional application pertains, the feeding pins are adiustably mountedon an end-.

lesstraveling .chain or belt, and are carried over.

. an elongated cam or track by which they are circuitous carrier for theGil automatically projected through the holes in the recordmateriaLandat the limit of which they are automatically retracted therefrom.

The construction disclosedand claimed in the parent application brieflydescribed, comprises a platen roll ill for use in a writing orimprinting machine having at each end thereof pin wheel units 20 whichform continuations of the platen roll. Extending axially through theplaten roll i0 and pin wheelunits 20 is a shaft I! on which 1 the platenroll is mounted for unison rotation spaced relation for oscillatorymotion upon trunnions 26 are annular series of oscillatory elbow levers,comprising outer arms 28 which form feeding pins for engagement inlongitudinally spaced holes in the record material to be fed, and innerarms 32 which control the extension and retraction of the pins 28. Thestrip engaging feeding pins 28 may be straight, and are preferablytapered to a blunt or rounded point as shown in Figs. 8 and 9, or may beprovided with enlarged heads or cross arms 38, as illustrated in detailin Fig. 7 and as shown in Figs. 1 to 4.

Forthe present purposeeither form may be employed, but the form shown inFigs. 8 and 9 is preferred, since this form does not necessitatespecially shaped feed holes as shown in Fig. 6

for reception of the headed style of pins, but is usable with stationeryhaving relatively spaced round holes such as is now extensively used formanifolding purposes.

The inner unaligned arms 32 of the feeding pins 28 engage with a cam 34stationarily supported within the platen on the tubular sleeve 24 as theplaten rotates thereabout. During the greater portion of their circularpath of travel about the cams, the feeding pins are held 'retracted, asshown at A in the several views, by individual retractile sp gs 56.When, however, the innerarms 32 of the feeding pins engage the highpoint of the cam 34, they are progressively oscillated about theirpivotal connections 26 against the tension of the springs 56 intoextended position as shown at B. The periphery of the pin wheel unit isprovided with slots or "openings corresponding approximately to the ingsin the peripheries of the pin wheel units comprise T-shaped slots, asshown in Fig. 1, thus permitting the cross heads to be swung from the inposition A to the out position B, as clearly shown in Figs. 2 and 4. Thestraight pin s 28 illustrated in Fig. 9 necessitate only short straightslots extending peripherally of the pin feed the stationery in asubstantially straight path of travel, either in its approach toward orits departure from the writing or imprinting position. To this end, pinsof either the form shown in Fig. 7 or Fig. 9 may be mounted upon endlesstraveling chains or belts relative'to which the feeding pins are movableinto engagement in holes in the record material and retracted. therefromincident to their travel movement at l predetermined points in theirpaths or travel.

Referring to this form of pin type feeding means disclosed in Fig. 5,the same type pins shown in Figs. 1, 2, 3, 4 and 7 have been shownmounted on a continuous chain trained over relatively spaced sprockets62 and B4. The feeding pins 29 are projected to the out position bytheir travel movement over a cam 66 underlying a portion of the chain'60 during which the pins are projected into engagement with the recordmaterial to feed the same in a straight path. The feedin pins 29 arepivotally mounted in the chain for oscillatory motion into and out ofrecord material engaging relation. The engagement of their arms.32 withthe cam 66 serves to oscillate the pins 29 to erect position and to sohold them while the pins traverse the length of the cam 66.

When the feeding pins pass beyondthe cam 60, springs 68 similar. to thesprings 56 illustrated in Fig. 4 retract the pins out of engagement withthe record material. Feeding pins of eitherjthe type shown in Fig. 7 orFig. 9 may be employed,- in the circuitous chain belt type of feedingdvice shown in Fig. 5. In Fig. 9, a record material feeding arm 10 ofstraight construction tapering to a blunt or rounded end without theextensions 30 is shown. The arm 32 thereof by its engagement with eitherthe cam 34 or the cam 66, according to the type of device, 'controlstheextension and retraction of the feeding pins into and out of engagementin the longitudinally spaced holes in the record material. Such type offeeding pin may be used with record materialv having either round oroblong apertures. 4

The endless belt or chain pin type feeding device may be locatedparallel to the path of travel of the record material to engagetherewith either in advance or beyond the imprinting position.

The feeding pins are progressively extended and retracted into and outof longitudinally spaced holes in the record strip while advancing it ina relatively straight path of travel. 3' From the above description itwill be apparent that there is thus provided a device of the characterdescribedpossessing the particular features of advantage beforeenumerated as desirable-but.

which obviously is susceptible of modification in 1ts form, proportions,detail construction and .51 arrangement of parts without departingfIOlIirjL-i means is employed, the rock sleeve 24 is so adjusted thatthe pins are projected at an inoperative position slightly rearwardly ofthe top of the platen roll, as shown in Fig. 3.

Such projection of the feeding pins in opera-"' tive or inoperativeposition at the will of the operator is shown and described in LettersPatthe principle involved or sacrificing any of itsi advantages.

While in order to comply with the statute, the? invention has beendescribed in language more, or less specific as to structural features.it is 'toi tion with the path of travel of the belt governing theextension and retraction of the pins.

be understood that the invention is not limited to the specific featuresshown, but that the'means and construction herein disclosed comprise thepreferred form of several modes of putting the invention into effect.and the invention is therefore claimed in any of its forms ormodifications within the legitimate and valid scopeof the appendedclaims.
